Thread: 3.5" LCD Touchscreen

  1. #1

    Default 3.5" LCD Touchscreen

    I just installed a 3.5" TSLCD to monitor data from a HP ECU. I've been having trouble with oil & fuel pressure gauge display. Gauges are labeled and displayed on screen, but no data of actual pressure. In other words the gauges are blank. Help would be greatly appreciated. Currently using V5 latest firmware.

    It probably isn't programmed to the proper channel. The EFI (laptop) software, ECU firmware & touchscreen unit must all be version compatible (LINK).

    Thank you Danny. I'll try to update the 3.5" TSLCD. Once I download how to update the touchscreen.

    I had to think for a change. I removed the SD card from TSLCD, loaded update on SD card. Reinstall SD card, boot screen up and it looks like the update took place. Thank you.

    I am having problems with 3.5 LCD screen randomly switching screen displays when my motorcycle is running, any thoughts of possible causes ? Screen is mounted in a vibration type mount. This is the second time using the screen during a TNT session, 1st time out no issues.
